Imagine a battery powered bugging device, voice recorder, or GPS tracker that never needs to have it's battery changed or charged.

City Labs says, "...the company’s team of scientists and engineers has developed batteries
with a 20+ year lifetime of continuous power without the requirement
for replacement or recharging. The NanoTritium™ battery can energize a
broad range of devices where battery replacement is difficult,
impractical, or even life-threatening."
The power cell generates electricity using a layer of the radioactive-element tritium, mounted onto a semiconductor.

| Next generation. |
The City Labs’ battery produces nanowatts of power; it is not strong enough to power a cell phone or laptop. This is a low-power battery that can run micro-electronics, anywhere that is hard, dangerous or expensive to reach. Applications include implants such as pacemakers as well as devices in industry (sensors on deep-water oil drills) and defense. (more)
Currently, these batteries, "...are used to keep encryption keys alive in SRAM for more than 20 years...". A second generation (coming soon) will be able to do a whole lot more.
